Two forces of 50 and 68 pounds act on a body to produce a resultance force of 70 pounds. Find, to the nearest ten minutes or nearest tenth of a degree, the angle formed between the resultance force and the smallest force.
TEXTBOOK DEFINITION OF RESULTANT:
If two forces act at the same time on a body, the single force that has the same effect as these two, called resultant, is the diagonal of a parallelogram whose adjacent sides represent the two forces.
Here's a hint
Hint: Use law of cosines A^2 + B^2 - 2AB cos (angle AB) = C^2. You already know the lengths of the sides.
Great
Great hint. I can take it from here.
